This is where the decision actually gets made, so it's worth working through carefully rather than trusting a single headline number.
Etsy's fee stack has more moving parts than people expect, a $0.20 listing fee that renews every four months (or whenever an item sells, whichever comes first), a transaction fee of roughly 6.5% on the item price plus shipping, and payment processing on top of that, commonly around 3% + $0.25 for US sellers using Etsy Payments. If a sale comes through Etsy's Offsite Ads program, add another cut: 15% for sellers under $10,000 in trailing annual sales, dropping to 12% above that threshold, and this program becomes mandatory once you cross that revenue line, not optional.
Shopify's fee stack is simpler by design, a flat monthly subscription ($29/month on Basic with annual billing, $39 month-to-month), plus standard card processing if you use Shopify Payments directly (2.9% + 30¢ on Basic, dropping on higher tiers) with no additional platform fee on top. Route payments through a third-party gateway instead, and Shopify adds a separate fee roughly 0.5% to 2% depending on your plan.
Run the math as a formula, not a single example - since the exact numbers move with your price point. Etsy's per-order cost is - listing fee ($0.20) + (6.5% × item price and shipping combined) + payment processing (roughly 3% + $0.25). Shopify's per-order cost, if you're on Basic with Shopify Payments, is just processing: 2.9% + 30¢, with nothing layered on top. The structural difference is what matters more than any single dollar figure: Etsy's cost is almost entirely variable, scaling with every sale, while Shopify's is mostly fixed (the subscription) with a much smaller variable component per order.
That structure has one major asterisk sellers routinely underestimate, Offsite Ads. Once a shop crosses $10,000 in trailing annual sales, Etsy requires participation - any sale attributed to one of those ads carries an additional 12–15% on top of the standard fee stack, and there's no opt-out once you're past that threshold. A seller who's grown past that mark and gets a meaningful share of sales through Offsite Ads can end up paying close to a quarter of an order's value in combined fees, even though the "headline" Etsy fee structure looks closer to 10% on paper.
It's worth being fair to Offsite Ads here, though, not just critical of it. The fee only applies when the ad actually produces a sale, you're not paying per click the way you would running your own Google or Meta ads on Shopify, where the budget disappears whether or not anyone buys. For a seller without the time or expertise to manage a paid-ads account themselves, Offsite Ads functions as a no-risk-of-wasted-spend version of advertising, even if the effective cost per conversion ends up higher than a well-run campaign a more experienced marketer could build on their own.
Where this nets out for a typical seller: somewhere in the range of 10–12 orders a month is usually enough for Shopify's flat subscription to be fully offset by its lower variable cost per order, though the exact crossover shifts with your average order value, shipping charges, and how dependent your Etsy sales are on paid Offsite placement versus organic search. Below that volume, Etsy's mostly-variable cost structure tends to come out cheaper. Above it, the fixed-cost model on Shopify starts working increasingly in your favor.
